Embodiment Construction
[0019] Below in conjunction with accompanying drawing, the present invention will be further described.
[0020] The technical problems involved in the present invention are solved by the following technical solutions: a production method of high-silicon electrical steel, the specific production process is:
[0021] (1) Smelting molten steel with two components, one with a silicon content of 2.0% to 3.5%, the other with a silicon content of 4.5% to 7.0%, and the other components in the steel are the same as the target components.
[0022] (2) Continuous casting is used to cast molten steel into billets, and the superheat of molten steel is 10-30°C; a drainage device 1 is installed in the continuous casting crystallizer 5, and one end of the drainage device 1 is open and the opening is downward, and the interior of the drainage device 1 is empty cavity 4, the drainage device 1 is suspended in the molten steel, and a gap of 10 to 40 mm is formed between the outer wall of the dra...
